What's better than riding your bike to work? Riding your bike to a party.

And on June 27, you'll have the opportunity to do both. The fourth annual Cactus Bike From Work Bash encourages you to ride to work, then meet up at 15th and Little Raven downtown at 5:00 p.m. for a rowdy good time.

If you're on the fence, check out this year's just-released promo video titled "Bikes Love Bikes," above. It's awfully... seductive.

Cactus promises free beer, food, and entertainment. Previous years events have included bike raffles, bike valet, trick competitions, at least one appearance by a penny farthing (the old-school bikes with one big wheel in front), and at least one sexy bike wash (see below).

Should you require new duds for the outing, Primal Wear will manufacture a limited run of Cactus-designed bike jerseys for the event. The jerseys cost $75, with all proceeds going to benefit Bike Denver, a bike-advocacy nonprofit.

The 2011 Bike From Work Bash had an estimated attendance of 3,000 people, and raised $1,800 for BikeDenver.
